. To all whom t may concern.'

Be it known that I, PERCIVAL GREEN, a citizen of the United States,residing at San Francisco, in the county of San'Francisco and State ofCalifornia, have invented certain new and useful Improvements in Meat-Blocl-Surfacing Machines, of whichthe following is a specification.

This invention relates to surfacing machines and, more particularly, toapparatus for cutting the top of a butchers meat block to a planesurface when the same becomes uneven or rough through use.

The object of the present invention is to provide elicient devices ofthis character which will be convenient to operate andymay be readilyapplied t0 or detached from a meat block.

The invention consists in the novel construction, adaptation andcombination of devices as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 i is a plan view showing a meatblock with my invention applied thereto. Fig. 2 is a side elevation ofthe same. Fig. 3 is a dew tail vertical section through 3-3 of Fig. 1,and Fig. 4 is a horizontal sectional View through a cable winding barreland its spindle to illustrate the manner of securing the barrel to thelatter and for taking up slack from the cable.

In said drawings, the reference numeral 5 designates a butchers meatblock, the top g1 o-f which is to be dressed to anplane surace.

According to my invention I provide a box-like frame 6 which may beconstructed of cast iron and is provided upon its front wall 61 with aplurality of conical protuberances 7 which serve to penetrate into aside of the block to prevent the frame tilting in a lateral directionwhen it is firmly clamped against the block. The clamping of said frameto the block is attained by means of a cable S which embraces the blockby a loop, as indicated in Figs. 1 and 2, and has its ends respectivelyengaged with and then Wound about barrels 9 and 91 which are mountedupon upright spindles 10 and 101 which are j ournaled in the frame 6 inproximity to the corners remote from the wall 61 which is juxtaposedwith the block. These spindles are provided with polygonal `upper ends101 toenable them to be engaged by a wrench or a handle provided with asuitable socket. Intermediate the lengths of said spindles they are eachprovided with a hole 103 (Fig. 1) extending diametricall-y therethroughand a similarly arranged hole 92 is provided in each of the barrels.`

When the frame is to be attached to a Vblock it is heldrk against thelatter, and the f cable looped about the block and the cable endsthreaded through the holes of the respective barrels and spindles. Theends are then furtherpdrawn by the operator through the said holesuntil' the slack is removed from the cable loop and the frame isthereupon rigidly clamped to block by successively turning the spindlesthrough the medium of the referred to wrench or handle.

In such operation it is evident that the cable by passing through thebarrels and the spindles, will couple them together and by such.coupling meansthe size of the loop in the cable may be readily variedto accommodate blocks of diiferent diameters and shapes.

11 represent ratchet wheels secured to the spindles and are engaged bypawls 12 which are pivotally connected to said frame to pre` vent anyaccidental unwinding of the cable from the barrels. Extendinglongitudinally through the frame is a screw 13 which engages in a nut 11(Fig. 3) havinga socket 141 in its top to serve as a seat for thespherical lower end 151 of a cylindrical-post 15. This post extendsthrough an aperture 16 in a nut 161 which engages the threads of a screw17 extending transversely through the frame. Said screws are providedwith polygonal ends 131 and 171 whereby they may be rotated by a wrenchand are secured against axial 'movements by set collars 132 and 172. Bysuitably regulating the nuts 11 'and 16 throughthe instrumentality ofthe respective screws, the post 15 may be adjusted to be in a verticalposition or in a position rectangular to the plane to which it isdesired to dress the top of the meat block, even though the frame itselfmay be considerably tilted from the horizontal. The post 15 serves as apintle for a substantially horizontal arm comprising two members 18 and181 which are jointed or connected together by a hinge pin 19.

At the free end of the outer arm member 181 are provided bearings for anupright arbor having v*mounted atdit's lovver end a circular saw 21.Said arbor is driven by an electric motor of ordinary or suitable"structure which is inclosed in a casing l22 regulated, the operatorcompletes the 'electric circuit to I'rotate the saw which thencontrolled by the v:operator lto cause it to traverse the'top of theblock by swinging the saine about the axes of "the post A and theelboivjoint of the arm. The saw is most conveniently movable through theagency of 'the 'handle bar 24.

1. *Af block dressing device of the characte'r described, comprising aframe, Ine'ans for fdetaclhably securing said fra-me to a block, 'fapost, means provided in said frame for regulatingthe angular position ofsaid post with respect to the traine, a jointed arm supported by y'SdPost an arbor ucar' i ried by the outer vend oit said arm, a saw`mounted on 'said arbor, 'and a rr'iotor for rotating the saw throughthe medium of said ar or.

2. In a block dressing machine, the combination With an upright arbor, asaW mount- -ed thereon, means to drive said arbor and the saw, an armcarrying said arbor and the driving means, and a post supporting saidarm, of a frame, a step-bearing provided in the frame Jfor the post, lapost journal bearing provided in the frame above said step-bearing,means for adjustably moving Ysaid journal and step-bearing in'rectangular relations to each other, yand means to detachably securesaid frame to a block vvhich is to 'be dressed.

3. In apparatus of the class described, the combination with an uprightpost, 'a saw, driving means for the saw, and operative connectionsbetween said post and the saw to enable the latter to be swung in ahorizontal plane, 'a frame, means provided in said frame for supportingthe post in various adjusted positions,'and means for clampingsaid framefto the block to be dressed.
